Florida university shuts down campus after shooting

Florida Atlantic University in Boca Raton, Fla., closed its campus and activated newly installed warning sirens Wednesday after a shooting at student apartments on the campus.

No one was injured in the incident, but university police were searching for the gunman and placed the campus, north of Miami, on lockdown as a precaution.

"Only Tier 1 essential personnel are permitted on campus," the university announced in a bulletin on its Web site.

The sirens and a new public address system were part of a security system installed at the campus after last year's shootings at Virginia Tech left 32 students dead.
